Abstract

Standard measures of image quality are used to quantify the effect of atmospheric turbulence on specific target and background signatures from digital images. The degraded signature corresponding to any atmospheric coherence diameter can be computed with a direct convolution model developed in previous work. Image analysis software has been developed to compute image quality factors by comparing the original and degraded signatures. Regions of maximum clutter can also be be located and evaluated with the image quality factors. Results are presented for signatures gathered with a FLIR imaging sensor under typical field conditions.
